Glucose alters symbiotic relationships between gut microbiota and host physiology.

Bacteria and mammals exhibit all aspects of symbiosis. Metabolic flux in bacteria and in specific host cells can influence host-microbe symbiotic relationships and tip the balance between mutualism, commensalism, and parasitism. The relationship between microbes and host metabolism is bidirectional: microbes can influence host blood glucose, but glucose levels can influence the microbiota and host response and outcomes to specific bacteria. A key consideration determining symbiotic relationships is compartm...


The Gut Feeling: GPCRs Enlighten the Way.

Host-microbiome interactions affect host physiology, but the underlying mechanisms are not well understood. Recent papers from Chen et al. (2019) and Colosimo et al. (2019) in this issue of Cell Host & Microbe demonstrate that metabolites produced by several members of the gut microbiota can efficiently activate host G protein-coupled receptors and influence host physiology.

The role of the gut microbiota in the treatment of inflammatory bowel diseases.

The human intestinal microbiota coevolves with its host through a symbiotic relationship and exerts great influence on substantial functions including aspects of physiology, metabolism, nutrition and regulation of immune responses leading to physiological homeostasis. Over the last years, several studies have been conducted toward the assessment of the host-gut microbiota interaction, aiming to elucidate the mechanisms underlying the pathogenesis of several diseases. A defect on the microbiota-host crosstal...


Beyond host regulation: Changes in gut microbiome of permissive and nonpermissive hosts following parasitization by the wasp Cotesia flavipes.

Koinobiont parasitoids regulate the physiology of their hosts, possibly interfering with the host gut microbiota and ultimately impacting parasitoid development. We used the parasitoid Cotesia flavipes to investigate if the regulation of the host would also affect the host gut microbiota. We also wondered if the effects of parasitization on the gut microbiota would depend on the host-parasitoid association by testing the permissive Diatraea saccharalis and the nonpermissive Spodoptera frugiperda hosts. We d...

Perfluorooctane Sulfonate Alters Gut Microbiota-Host Metabolic Homeostasis in Mice.

Perfluorooctane sulfonate (PFOS) is a persistent environmental chemical whose biological effects are mediated by multiple mechanisms. Recent evidence suggests that the gut microbiome may be directly impacted by and/or alter the fate and effects of environmental chemicals in the host. Thus, the aim of this study was to determine whether PFOS influences the gut microbiome and its metabolism, and the host metabolome. Four groups of male C57BL/6 J mice were fed a diet with or without 0.003%, 0.006%, or 0.012%...

Dietary lipids, gut microbiota and lipid metabolism.

The gut microbiota is a central regulator of host metabolism. The composition and function of the gut microbiota is dynamic and affected by diet properties such as the amount and composition of lipids. Hence, dietary lipids may influence host physiology through interaction with the gut microbiota. Lipids affect the gut microbiota both as substrates for bacterial metabolic processes, and by inhibiting bacterial growth by toxic influence. The gut microbiota has been shown to affect lipid metabolism and lipid ...

Assessment of gut microbiota fecal metabolites by chromatographic targeted approaches.

Gut microbiota, the specific microbial community of the gastrointestinal tract, by means of the production of microbial metabolites provides the host with several functions affecting metabolic and immunological homeostasis. Insights into the intricate relationships between gut microbiota and the host require not only the understanding of its structure and function but also the measurement of effector molecules acting along the gut microbiota axis. This article reviews the literature on targeted chromatograp...

Characterizing symbiont inheritance during host-microbiota evolution: application to the great apes gut microbiota.

Microbiota play a central role in the functioning of multicellular life, yet understanding their inheritance during host evolutionary history remains an important challenge. Symbiotic microorganisms are either acquired from the environment during the life of the host (i.e. environmental acquisition), transmitted across generations with a faithful association with their hosts (i.e. strict vertical transmission), or transmitted with occasional host-switches (i.e. vertical transmission with horizontal switches...

Helminth-microbiota cross-talk - a journey through the vertebrate digestive system.

The gastrointestinal (GI) tract of vertebrates is inhabited by a vast array of organisms, that is, the microbiota and macrobiota. The former is composed largely of commensal microorganisms, which play vital roles in host nutrition and maintenance of energy balance, in addition to supporting the development and function of the vertebrate immune system. By contrast, the macrobiota includes parasitic helminths, which are mostly considered detrimental to host health via a range of pathogenic effects that depend...

Acidic pH promotes lipopolysaccharide modification and alters colonization in a bacteria-animal mutualism.

Environmental pH can be an important cue for symbiotic bacteria as they colonize their eukaryotic hosts. Using the model mutualism between the marine bacterium Vibrio fischeri and the Hawaiian bobtail squid, we characterized the bacterial transcriptional response to acidic pH experienced during the shift from planktonic to host-associated lifestyles. We found several genes involved in outer membrane structure were differentially expressed based on pH, indicating alterations in membrane physiology as V. fisc...

Evidence for host effect on the intestinal microbiota of whitefish ( sp.) species pairs and their hybrids.

Investigating relationships between microbiota and their host is essential toward a full understanding of how animal adapt to their environment. Lake Whitefish offers a powerful system to investigate processes of adaptive divergence where the dwarf, limnetic species evolved repeatedly from the normal, benthic species. We compared the transient intestinal microbiota between both species from the wild and in controlled conditions, including their reciprocal hybrids. We sequenced the 16s rRNA gene V3-V4 region...

Characterization of the Rat Gut Microbiota via 16S rRNA Amplicon Library Sequencing.

It is becoming increasingly apparent that microbiota have measurable effects on numerous phenotypes in laboratory animals. This "second genome" has often been disregarded or ignored due to its commensal nonpathogenic nature, and the difficulty, expense, and analysis of sequence. Recent advances in sequencing methods and analyses of large datasets have made characterization of microbiota populations routine and have uncovered previously unknown relationships of microbial communities and host biological syste...

Microbiota-Nourishing Immunity: A Guide to Understanding Our Microbial Self.

In ecological terms, the microbiome is defined as the microbiota and its environment, a definition that encompasses the human host. The size, species composition, and biogeography of microbial communities is shaped by host interactions, and, in turn, the microbiota influences many aspects of human health. Here we discuss the concept of microbiota-nourishing immunity, a host-microbe chimera composed of the microbiota and host factors that shape the microbial ecosystem, which functions in conferring colonizat...

The role of commensal microbes in the lifespan of .

Commensal microbes have mutualistic relationships with their host and mainly live in the host intestine. There are many studies on the relationships between commensal microbes and host physiology. However, there are inconsistent results on the effects of commensal microbes on host lifespan. To clarify this controversy, we generated axenic flies by using two controlled methods - bleaching and antibiotic treatment - and investigated the relationship between the commensal microbes and host lifespan in . The re...

Effects from diet-induced gut microbiota dysbiosis and obesity can be ameliorated by fecal microbiota transplantation: A multiomics approach.

Obesity and its comorbidities are currently considered an epidemic, and the involved pathophysiology is well studied. Hypercaloric diets are tightly related to the obesity etiology and also cause alterations in gut microbiota functionality. Diet and antibiotics are known to play crucial roles in changes in the microbiota ecosystem and the disruption of its balance; therefore, the manipulation of gut microbiota may represent an accurate strategy to understand its relationship with obesity caused by diet. Fec...

Disentangling the effect of host genetics and gut microbiota on resistance to an intestinal parasite.

Resistance to infection is a multifactorial trait, and recent work has suggested that the gut microbiota can also contribute to resistance. Here, we performed a fecal microbiota transplant (FMT) to disentangle the contribution of the gut microbiota and host genetics as drivers of resistance to the intestinal nematode Heligmosomoides polygyrus. We transplanted the microbiota of a strain of mice (SJL), resistant to H. polygyrus, into a susceptible strain (CBA) and vice-versa. We predicted that if the microbio...

Body-site specific microbiota reflect sex and age-class among wild spotted hyenas.

Host-associated microbial communities, henceforth 'microbiota', can affect the physiology and behavior of their hosts. In mammals, host ecological, social, and environmental variables are associated with variation in microbial communities. Within individuals in a given mammalian species, the microbiota also partitions by body-site. Here, we build on this work and sequence the bacterial 16S rRNA gene to profile the microbiota at six distinct body-sites (ear, nasal and oral cavities, prepuce, rectum, and anal...

Diet-microbiota interactions and personalized nutrition.

Conceptual scientific and medical advances have led to a recent realization that there may be no single, one-size-fits-all diet and that differential human responses to dietary inputs may rather be driven by unique and quantifiable host and microbiome features. Integration of these person-specific host and microbiome readouts into actionable modules may complement traditional food measurement approaches in devising diets that are of benefit to the individual. Although many host-derived factors are hardwired...

The Role of the Microbiome in Drug Response.

The microbiome is known to regulate many aspects of host health and disease and is increasingly being recognized as a key mediator of drug action. However, investigating the complex multidirectional relationships between drugs, the microbiota, and the host is a challenging endeavor, and the biological mechanisms that underpin these interactions are often not well understood. In this review, we outline the current evidence that supports a role for the microbiota as a contributor to both the therapeutic benef...

Gut microbiota - host interactions now also brain-immune axis.

The 'gut-brain axis' is a fairly new term in the fairly new field of the gut microbiota. The gut microbiota, the collection of microorganisms residing in intestines of vertebrates, was shown to have major effects on host physiology. The field has seen a renaissance due to advances in deep-sequencing. Recently, there is an explosion of studies on the physiological and therapeutic potential of the gut microbiota. These microbes are considered to reside in symbiosis with their hosts, and are termed 'commensals...

Transitions and transmission: behavior and physiology as drivers of honey bee-associated microbial communities.

Microbial communities have considerable impacts on animal health. However, only in recent years have the host factors impacting microbiome composition been explored. An increasing wealth of microbiome data in combination with decades of research on behavior, physiology, and development have resulted in the European honey bee (Apis mellifera) as a burgeoning model system for studying the influence of host behavior on the microbiota. Honey bees are eusocial insects which exhibit striking behavioral and physio...

Dysbiosis: from fiction to function.

Advances in data collection technologies reveal that an imbalance (dysbiosis) in the composition of host-associated microbial communities (microbiota) is linked to many human illnesses. This association makes dysbiosis a central concept for understanding how the human microbiota contributes to health and disease. However, it remains problematic to define the term dysbiosis by cataloguing microbial species names. Here we discuss how incorporating the germ-organ concept, ecological assumptions and immunologic...

Helicobacter spp. in Experimental Models of Colitis.

The colonization of body surfaces, notably of the intestine, by a complex microbiota is generally highly mutualistic, where vital functions are provided by the commensal microbiota to the host, including the synthesis of vitamins, the degradation of complex polysaccharides into small chain fatty acids (which are essential for the maintenance of the intestinal epithelial barrier), and, finally, the outcompetition of pathogens that accidentally gain access to the body ("colonization resistance") (Chow et al. ...

Lower Circulating Branched-Chain Amino Acid Concentrations Among Vegetarians are Associated with Changes in Gut Microbial Composition and Function.

Vegetarian diets confer health benefits to many cardiometabolic diseases, while whether and how gut microbiota in vegetarians contributes to host metabolism remains unclear. Thus, we aimed to explore the possible links between the gut microbiota and circulating gut microbiota-host co-metabolites among vegetarians and omnivores.

The Gut Microbiome in Bipolar Disorder and Pharmacotherapy Management.

The gut microbiome is a complex and dynamic community of commensal, symbiotic, and pathogenic microorganisms that exist in a bidirectional relationship with the host. Bacterial functions in the gut play a critical role in healthy host functioning, and its disruption can contribute to many medical conditions. The relationship between gut microbiota and the brain has gained attention in mental health due to the mounting evidence supporting the association of gut bacteria with mood and behavior. Patients with ...
